Among various alkaline solutions, K2CO3 has attracted more attention due to low heat of reaction, low toxicity, and large capacity and high selectivity for CO2 absorption. In the present research, we have obtained a K2CO3 based sorbent via thermal treatment of banana peel and then characterized for particle structure, morphology and chemistry using SEM, EDXA and FTIR techniques. This sorbent was then added to de-ionized water to perform CO2 absorption experiments in a closed chamber while circulating the atmospheric air via a CO2 sensor. The pH and conductivity of the sorbent solutions were measured before and after the CO2 absorption experiments, and then correlated to the amount of CO2 absorbed in order to understand the effect of initial pH on the kinetics of CO2 absorption process. These studies demonstrate a low cost solution for sequestration of CO2 while utilizing the organic waste from banana peel.
